OPTOLONG S-II 1.25 inch SII-CCD 6.5nm Narrow-Band Filter

If you're looking to capture stunning astro-photographs of deep sky objects, you might want to consider the OPTOLONG S-II 1.25 inch SII-CCD 6.5nm Narrow-Band Filter. This specialized filter is designed to only allow light from a specific range of wavelengths to pass through, specifically the SII emission line at 672.4nm, which is found in many nebulae.

With a narrowband filter like the S-II, you can effectively block out unwanted light pollution and capture incredibly detailed images of nebulae that would otherwise be difficult or impossible to photograph. The 6.5nm bandwidth is perfect for capturing detailed images of smaller targets, and the 1.25 inch size is ideal for use with a variety of telescopes and astrophotography setups.

The OPTOLONG S-II filter is constructed with high-quality materials, including Schott B270 optical glass with multi-layer coatings to ensure maximum light transmission and minimize reflections. The filter housing is made of precision CNC-machined aluminum with a black anodized finish, providing durability and resistance to corrosion.

Whether you're a professional astronomer or an amateur astrophotographer, the OPTOLONG S-II 1.25 inch SII-CCD 6.5nm Narrow-Band Filter can help you capture stunning images of nebulae and other deep sky objects with amazing detail and clarity.
